4. Karolina Kurkova

A lingerie model with no bellybutton? Well, Karolina Kurkova's absent navel can easily be explained by the fact that she’s clearly not of this Earth. Her incomparable beauty and renowned work ethic are why, at the age of 16, Kurkova was tapped for her first Victoria’s Secret fashion show. Over a decade later, her career is still going strong, and she’s parlaying her modeling success into a burgeoning acting career beginning with a role in G.I. Joe: The Rise of Cobra.
